MixedAfter 200 miles of long runs, a runner finds the Mach X 2 decently poppy but never comfortable, with heel slip and occasional numb feet.

MixedThe cushion and feel still seem fresh out of the box after 520 miles, unlike anything he's run. But the heel collar tore up his Achilles in the first runs. A cheap felt-pad fix '100% solved' it.

MixedA 3:20 marathoner loved the Mach X 2's fast midsole but returned it over heel issues, preferring the Cielo X1.
The Mach X 2 is a light, springy shoe that most runners enjoy for tempo and long runs. The main problem is the heel and ankle collar, which gives heel slip and Achilles blisters to a good share of wearers, though others have no issues. A few mention outsole wear.
